Abstract

Dans un défricheur classique par ailleurs, les lots de bois sont introduits dans la chambre de défrichage 3 par une chambre d'alimentation 6 munie de volets 14, 15 étanche à la pression que l'on ouvre et que l'on ferme successivement. Quand le volet 15 est ouvert, on introduit le bois dans la chambre d'alimentation puis on ferme le volet 15 et on ouvre le volet 14 pour faire tomber le bois dans la chambre de défibrage 3. Des vannes 18, 20 permettent de mettre la chambre d'alimentation à la pression atmosphérique ou à la pression de la chambre de defibrage. La pâte mécanique est déchargée de la chambre de défibrage par l'intermédiaire d'un sas à pression 22a constitué par la pâte mécanique elle-même. Application au défibrage en continu sous pression.In a conventional clearer, moreover, the batches of wood are introduced into the clearing chamber 3 by a feed chamber 6 provided with shutters 14, 15 pressure-tight which is opened and closed successively. When the shutter 15 is open, the wood is introduced into the feed chamber then the shutter 15 is closed and the shutter 14 is opened to let the wood fall into the defibration chamber 3. Valves 18, 20 are used to put the shutter. feed chamber at atmospheric pressure or at the pressure of the fiber chamber. The mechanical pulp is discharged from the defibration chamber via a pressure lock 22a formed by the mechanical pulp itself. Application to continuous defibration under pressure.
